不過記憶體時脈就大大提升至2GHz，足足比X1900XTX高出450MHz。另外，X1950XTX採用一款全新散熱器。參照X1900XT/XTX的設計作出改良，外型酷似IceQ3的設計，配備全銅用料增強散熱效能。而且，這款散熱器的重點在於靜音設計，在全負戰時發出的噪音比X1900XT/XTX時大大降低。不過當進入1920x1440@4xAA + 16xAF的測試環境時，X1950XTX的表現就大幅拋離7900GTX。由於在高解像度配合AA + AF的設定下，運算時需要大量的記憶體來進行缓衝之用。所以X1950XTX的2GHz記憶體時脈在這裡就可以發揮得淋漓盡致了。而X1950XTX及X1900XTX分別在《Serious Sam 2》及《COD 2》中，擁有比7950GX2更好的表現。所以採用單核心設計的X1950XTX及X1900XTX仍然是遊戲的王者！至於X1950XTX在技術上已有所突破，配搭了GDDR4記憶體後。為效能提供了直接的增長。
"与Radeon X1900XT相比，这款HIS的X1950XTX显卡采用了全新的散热器，这款散热器采用了风扇远离散热片以及风道优化设计，并且改进了风扇叶片以及马达设计，进一步降低了运行时的噪音。加上全铜的散热底座以及热导管，为显卡提供了良好的散热环境，为显卡工作在超高的频率下打下了基础。 " ... "这款HIS Radeon X1950XTX的定价为3799元，也是目前价格最低的Radeon X1950XTX显卡，性价比相当不错，非常值得推荐。在相关的测试中，这款显卡的性能表现出色，在所有的单核心显卡中占据了领先的地位，重新夺回了单核心显卡性能之王的宝座。虽然与Geforce 7950GX2显卡还有较大的差距，但是考虑到后者的售价普遍在5000元以上，那么两者的性价比自然也无可比性。如果你是ATI显卡的狂热FANS，那么这款不足4000元的顶级显卡将是你不容错过的产品。"
[Chip Recommended] The X1900XTX is presently the fastest card your money can buy, and it will remain the same in the next couple quarters.
[Editor's Choice] 記憶體方面兩者同樣為Samsung -1.1ns GDDR3，相比上代Radeon X1800XT採用的-1.2ns GDDR3顆粒有較大超頻空間，容量為512MB，規格最高可運作於1.8GHz時脈。新一代Compositing Engine主要改動在於PanelLink晶片，改用了Silicon Image的 SiI178 Transmitter及SiI163B Receiver，雖然兩顆晶片最高解像度都是UXGA頻寬為165MHz，因此最高可支援1600 x 1200，不過它們可同時用兩顆SiI178及SiI163B晶片並提升至Dual Link Resolution的QXGA解像度頻寬高達330MHz，因此最高解像度提升至2048 x 1536，完全解決了上代ATi CrossFire一直被垢病的解像度太低問題。從測試中可以看到ATi R580核心提升其Pixel Shader Processor數目至48個，效能上相比上代Radeon X1800XT的R520核心有著明顯的進步，証明ATi並非紙上談兵，而面對nVidia現時最強的7800GTX 512MB亦取得一定優勢，尤其是在高解像度並配合4倍FSAA時，原本為nVidia 7800GTX 512MB佔優的測試也被超越。另外，大家有沒有留意到在3DMark 06測試中，Geforce 7800GTX 512MB並不能運行4x AA測試!?其實Geforce 6或7系的HDR規格是按照OpenEXR的FP16規格設計，它會使用了核心原為FSAA而設的緩存作HDR運算之用，因此Geforce 6或7系並不可以令HDR和FSAA共存，而R5xx核心則透過把HDR和FSAA存緩分開放置，令HDR和FSAA能同時應用
